Semiclassical theory of spin transport in spin-orbit coupled systems
Dimitrie Culcer, Jairo Sinova, N. A. Sinitsyn +3
Motivated by recent interest in novel spintronics effects, we develop a semiclassical theory of spin transport that is valid for spin-orbit coupled bands. Aside from the obvious co…
Magnetization relaxation in (Ga,Mn)As ferromagnetic semiconductors
Jairo Sinova, T. Jungwirth, X. Liu +4
We describe a theory of Mn local-moment magnetization relaxation due to p-d kinetic-exchange coupling with the itinerant-spin subsystem in the ferromagnetic semiconductor (Ga,Mn)As…
First Principles Calculation of Anomalous Hall Conductivity in Ferromagnetic bcc Fe
Yugui Yao, L. Kleinman, A. H. MacDonald +5
We perform a first principles calculation of the anomalous Hall effect in ferromagnetic bcc Fe. Our theory identifies an intrinsic contribution to the anomalous Hall conductivity a…
Universal Intrinsic Spin-Hall Effect
Jairo Sinova, Dimitrie Culcer, Q. Niu +3
We describe a new effect in semiconductor spintronics that leads to dissipationless spin-currents in paramagnetic spin-orbit coupled systems. We argue that in a high mobility two-d…
Orbital Effects of In-Plane Magnetic Fields Probed by Mesoscopic Conductance Fluctuations
D. M. Zumbuhl, J. B. Miller, C. M. Marcus +3
We use the high sensitivity to magnetic flux of mesoscopic conductance fluctuations in large quantum dots to investigate changes in the two-dimensional electron dispersion caused b…
Exact diagonalization study of domain structure in integer filling factor quantum Hall ferromagnets
E. H. Rezayi, T. Jungwirth, A. H. MacDonald +1
Opposite spin Landau levels in a quantum well can be brought into coincidence by tilting the magnetic field away from normal orientation. We demonstrate that the magnetotransport a…
